The invention discloses an upper rack construction operating car for a storage power station, and relates to the field of storage power station construction equipment. According to the technical scheme, the upper rack construction operating car for the storage power station comprises a rail and the operating car which can operate along the rail, the rail is annularly arranged along the upper edge of a power generator well, a lifting displacement mechanism controlled by a manually operated clutch is arranged on the operating car, and the lifting displacement mechanism is connected with the rail; and the rail comprises an upper slide rail and a lower slide rail which is arranged on the lower side of the upper slide rail, and the upper slide rail is arranged on the upper edge of the power generator well. The construction operating car on the rack of the storage power station has the beneficial effects of being convenient to use and reasonable in design, by combining a rack well of a power generator, and additionally mounting the rail on the original basis, an existing power generator can be mounted and used conveniently on the basis of the original structure not being damaged, independent power supply is not needed by the whole device, the operating car is completely manually operated by workers, and can be suitable for the power off state when the power generator is repaired; the integral height and horizontal position of the device can be correspondingly adjusted by the workers standing in operating boxes and rocking a handle, and the whole using process of the device is safe and simple. Meanwhile, lifting and horizontal movement can be switched to operate through a simple clutch mechanism, and the operating car is convenient and easy to use.
